In one way or another, every single thing on this earth is dependent on one thing, and that is “The Sun.” We can’t survive on this beautiful earth without the sun.
Sun is far away from the earth, but the heat and light from the sun prevent the earth from being an ice-coated lifeless planet. The sun helps our plants to sustain life. Moreover, it controls our weather patterns. We use different meteorological instruments to determine or get accurate data on the weather, but all these would have gone in vain if there was no sun.
The sun has a great effect on the earth along with its weather. The effects most of the time are advantageous, but sometimes this sun becomes the reason for suffering.
Without any due, let’s discuss the effect of the sun on the earth and the weather, which will give a view of how vital the sun is for the sake of our existence.
The energy that the earth gets from our sun is significant. The sun keeps our planet warm and prevents it from being only an ice-coated rock.
In the primitive age, people used to worship the sun as they were afraid of losing the sun during the eclipse. Later on, scientists studied and invented different solar instruments that give data and information about the sun and its actions and importance in every aspect.
We get the required amount of heat and light from the sun, and any disturbance in its regulation will severely affect the earth. For this reason, people used to pray to the sun and sacrificed different things for it.
Sun has the most significant impact on the stratosphere, one of the layers of the earth’s atmosphere. This is also called the ozone layer.
This layer protects the earth from many harmful gases and chemicals coming from the sun and allows only benefits. Stratosphere also reduces ultraviolet rays to a certain extent.
This is a layer under the stratosphere where the weather occurs. The surface of the troposphere becomes hot when the lower stratosphere is heated.
When the troposphere is cold, and the planet’s surface is hot, it creates a temperature difference that leads to storms and hurricanes.
This layer surrounds the earth like a shield and protects the earth from electrolytes that are charged particles and plasma. This layer induces the electrical current in the atmosphere and the ground.
These are the particles that come from the sun at a high rate of speed, and when they pass through the human and the atmosphere, they will cause a genetic change in humans and can damage the satellite’s electronics.
Usually, the layers of the atmosphere save the earth from these harmful particles.

Our sun is a massive source of energy, and it continuously emits its energy into space. Some of its energy enters the earth through radiation.
Solar radiation that seems to be a short wavelength and of ultraviolet type can be dangerous when it crosses all the layers of the atmosphere and enters the earth’s surface.
When the earth’s surface absorbs solar radiation, it begins to heat up, and the earth’s air also starts absorbing the radiation. It is said the particle that absorbs faster also emits at a quicker rate.
The air then emits radiation in a longer wavelength in the atmosphere that warms up the earth’s surface, and for this, the earth’s surface is warmer than the air above us.
On the first day of spring, it lies directly over the equator, and solar radiation is received vertically when it is over the equator.
But if you proceed through the north and south of the equator, the radiation comes at lower angles. The lower the angles, the less energy is received, which means less energy is needed to warm up the air.
This might seem that the equator will face hot all year, which will be cool in the polls. But all of us know that, throughout the year, the temperature is not the same.
This is because the earth rotates to its axis. Thus during summer, it is hot in the northern hemisphere, while in the southern hemisphere, it is cold as the sun’s angles are much lower.
We know that after every six months, the seasons change as the earth changes its direction about the earth. After six months Thus, the season and the weather vary because of the sun’s and the earth’s rotation.
Sun has a great impact on our earth as well as other planets. Due to it, the earth is lively instead of rock or ice. That’s why we can see and feel the different seasons and sense the hot and coldness.
In fact, the sun is important for our existence on this earth and the life of the earth.
